Corporate Social Responsibility is key issue and under debate in the recent business world. In the developing countries, companies have to face serious consequences regarding implementation of Corporate Social Responsibility. Research on this topic is mostly done in developed countries. The first purpose of this study is to investigate “Does consumers consider CSR” and second part of this study focuses on Pakistan telecom industry analysis”. According to literature reviews from previous studies, it is proven that role of corporate social respon-sibility play vital role in the organization’s success. It was important to explore that does CSR have same role in telecom industry of Pakistan? This research involved a questionnaires survey conducted over 160 consumers of different telecom companies in Pakistan. Data were collected through verbal and non-verbal manner. Results showed that in Pakistan telecom industry corporate social responsibility has no role in the retention of consumers.

This manuscript analyses disputable aspects of the second postulate of the special theory of relativity. To verify them, the electric circuit theory is used. The respective theoretical and experimental research has proved that the statement of the special theory of relativity which denies that imaginary and complex numbers have physical meaning is incorrect. It is demonstrated that this misstatement of the special theory of relativity is refuted even by the fact of existence of such natural phenomena as tsunami, tolling of church bells, and others. Explanation of the physical meaning of imaginary and complex numbers is suggested. It is also proved that another statement of the special theory of relativity – the principle of light speed invariance – is restrictedly true; that is, it is incorrect in its current interpretation, and correct with the adjustments suggested herein. All the formulae describing relativistic effects are conditionally correct; that is, they are correct only with regard to our tardyon Universe, and incorrect with regard to all other parallel Universes that form the Multiverse. Ways of correcting these formulae are suggested.

This study analyzed theoretically the temperature distribution and energy storage ability of a simultaneous charging and discharging concrete bed Storage System. This was achieved by first modeled a single spherical shaped concrete which was used to represent a sequence of points along the axis of the beds. A one dimensional finite difference formulation was used in modeling the single spherical shaped concrete material, where heat conduction to neighboring spherical concrete was ignored. Using this assumption reduced the spherical shaped concrete model to that of an isolated sphere in cross flow, where the total surface area of the sphere was exposed to convection. The thermal properties of the materials within the bed accounted for temperature dependence. Comparisons were made between charging and discharging mode of the storage system for air flow rates of 0.0094m3/s, 0.013m3/s, and 0.019m3/s. It was discovered that the difference of the temperature response between the charging and fluid to solid heat transfer process at the initial period of the packed bed was large and the heat recovered by the cool air flowing inside the copper tube was fairly high (larger inlet–outlet temperature difference compared with the later period indicates larger heat recovery). The energy storage efficiency was also analyzed and it was discovered that spherical shaped concrete of 0.11m diameter has the highest storage efficiency of 60.5% at 0.013 m3/s airflow rate.

In a deregulated power system, the electric power demand is increasing day to day which may lead to overloads and loss of generation. Transient stability studies place an important role in power systems, which provide information related to the capability of a power system to remain in synchronism during major disturbances resulting from either the loss of generation or transmission facilities, sudden or sustained load changes. The analysis of transient stability is very important to operate the power system more secure and this paper focuses on increasing the transient stability [1] using FACTS devices like TCSC (Thyristor Controlled Series Capacitor), TCPAR (Thyristor Controlled Phase Angle Regulator), SVC (Static Var Compensator). These FACTS devices are optimally placed on transmission system using Sensitivity approach method. The proposed method is to enhance the transient stability on Modified IEEE-14 bus system and IEEE-24 bus system Using Power World Simulator 17 software.

The oral mucosa may be affected by a variety of systemic diseases and oral lesions most often may precede several mucocutaneous or systemic disorders. The systemic basis for many of the oral lesions is not clearly known. One such oral disease which may have a strong systemic basis for its pathogenesis is chronic desquamative gingivitis (CDG). In the literature there are conflicting reports as to the mechanism of pathogenesis of this clinical entity. Some investigators consider this as a unique clinical disease, whereas, others consider it as the gingival manifestation of disease processes having a strong correlation with the fluctuation of female sex hormones. This study was conducted to find out a correlation between circulating levels of serum estrogen (the female sex hormone) and occurrence of CDG in female patients.

This research paper attempts to study the portfolio performance evaluation of selected Hybrid growth schemes using Net Asset Values, Return, Beta and Standard Deviation and further used the risk adjusted evaluation methods such as Sharpe, Treynor, and Sortino Ratio. Researchers only emphasized on secondary data sources and selected 12 Mutual Fund schemes of 6 mutual fund institutions and the period of study is kept limited for 5 years i.e. from 2007-08 to2011-2012. To test the significance; F-test and Spearman’s rank correlation were used and found out that there is significant difference between NAV’s of two select categories, There is significant difference between scheme returns and benchmark returns of both Hybrid Equity Oriented (HEO) schemes and Hybrid Debt Oriented (HDO) schemes, there is mismatch between ranks of Risk and return of sample funds and the unique risk was meager. On the whole, the performance of the sample Hybrid funds during the study period was average.

Banking systems collect huge amounts of data on day to day basis, be it customer information, transaction details, risk profiles, credit card details, credit limit and collateral details, compliance and Anti Money Laundering (AML) related information, trade finance data, SWIFT and telex messages. Thousands of decisions are taken in a bank daily. These decisions include credit decisions, default decisions, relationship start up, investment decisions, AML and Illegal financing related. One needs to depend on various reports and drill down tools provided by the banking systems to arrive at these critical decisions. But this is a manual process and is error prone and time consuming due to large volume of transactional and historical data. Interesting patterns and knowledge can be mined from this huge volume of data that in turn can be used for this decision making process. This article explores and reviews various data mining techniques that can be applied in banking areas. It provides an overview of data mining techniques and procedures. It also provides an insight into how these techniques can be used in banking areas to make the decision making process easier and productive.

Usually Ottawa sand is used to find out in-situ density of soil by sand replacement method. Ottawa sand is very expensive and it is always imported from abroad. To avoid these difficulties the quality and suitability of locally available sand in and around Khulna district in Bangladesh in lieu of Ottawa sand were assessed for determining in-situ density using sand replacement method. Five samples of sand named by Sylhet sand, Kushtia sand, Fultala sand, Bogjhuri sand and Mongla sand were collected from nearby business centers. Original sand and some graded sands of each sample were under investigation to ascertain their suitability of use in lieu of Ottawa sand in determining in situ soil density. Five gradations were considered and those were (i) passing #16 and retained in #30, (ii) passing #30 and retained in #40, (iii) passing #40 and retained in #50, (iv) passing #30 and retained in #50 sieve and (v) passing #50 and retained in #100 sieve . Each of the original samples has been characterized by determining its index properties, grain size distribution. Specific gravity and density were determined for each sample of original and graded sands. These properties were compared with those recommended by ASTM (1989) for selecting suitable sand in sand replacement method. From this study it was found that original sands of all selected places in Bangladesh did not satisfy the ASTM (1989) criteria of Ottawa sand. In case of graded sands, Sylhet sand satisfied all the required ASTM criteria for four gradations except the gradation passing from #50 to #100 sieve, while Kushtia and Fultala sands satisfied fully for three gradations except the gradations passing from #16 to #30 sieve and passing from #50 to #100 sieve. Bogjhuri and Mongla sands did not satisfy all criteria. So, the graded sands that satisfy the criteria of Ottawa sand as mentioned in investigation may be used in sand replacement method in lieu of costly Ottawa sand.

Oneunique characteristic feature of the Yorubalanguage, spoken in South Western Nigeria is that when wordsare borrowed into it from other languages, such words arenativised. Some scholars have discussed the rules that applyin such cases. However, thiskind of study has not beenextended to Arabic names borne by Yoruba people (to thebest of my knowledge). This paper therefore discusses therules that apply on some of these names. Thirty Arabic names are purposively selected fordiscussion here. The theoretical framework adopted is naturalphonology which operates with phonological processes thatare deemed to constitute natural responses of human vocaland perceptual systems to the difficulties encountered in theproduction and perception of speech. Yoruba speakers apply some phonological rules onArabic names in an attempt to make them conform to thesyllable patterns of the Yoruba language. Vowel insertions oftwo kinds take place. The first kind is epenthetic in nature,because it involves the insertion of an extra medial vowel tobreak consonant clusters. The other kind takes place at theword final position. This is done to prevent consonants fromending names since the Yoruba syllable structure is essentiallyan open one. Consonant substitution takes place when theArabic consonant in a name is not attested in Yoruba. In someinstances, there seems to be a case of prothesis, theintroduction of an extra initial consonant. Tones are alsoimposed on every syllable. It is categorically clear that the same rules that applyon words that are borrowed from other languages to Yorubaalso apply on Arabic names commonly used by the speakersof the language, so the process is rule-governed and highlysystematic.

Background: Unwanted pregnancies and unsafe abortions are serious public health problems in the developing world, including Ethiopia. Until recently, safe abortion services were not available in Ethiopia, and little is known about the health providers’ attitude who is currently working in the abortion service provision. Assessing health care providers’ attitude and factors affecting their attitude towards safe abortion will help to focus on their solutions and facilitate of future safe abortion services. Objective: Was To assess health providers’ attitude and associated factors towards safe abortion service at Public Hospitals in Mekelle City, Tigray, Ethiopia. Methods: Institution based cross sectional study design was conducted using a quantitative method in Public hospitals, at Mekelle City, Tigray, Ethiopia. A self administered questionnnaire was used to collect the data. Pre-test was done for assuring Data quality. Data collectors were 5 nurses. The study population included: health officers, nurses, midwives, general practitioners, Obstetrician and Gynecologists. A probability proportional to size allocation was done. Systematic random sampling was employed to select the intended study subjects. Sample size was 243. Bivariate and multivariate logistic regression analysis was run to interpret and identify factors associated with attitude. OR, 95% confidence interval and p- value was calculated. Data entry, cleaning and analyzing was done by using SPSS version16 statistical software. Result: A total of 230 health providers’ had participated with a response rate of 94%. The odds of favorable attitude among the respondents who had good knowledge on abortion were 6.87 times the odds of the respondents who had poor knowledge on abortion [AOR=6.87, 95% CI (1.2, 39.90]. Similarly the odds of favorable attitude among the respondents who didn’t agree on the current Ethiopian law on abortion due to religious reason were 92% lower than the odds of the respondent
